The S40 gives you control over heating, cooling, fan operation and other everyday comfort settings.
You can manually adjust your heating or cooling temperature directly from the thermostat’s home screen.
If you’re using a programmed schedule, a manual temperature change may temporarily override your scheduled setting.
Your S40 can also use features such as Feels Like™, which considers both temperature and humidity when managing your home’s comfort.
Your S40 can help manage your home’s humidity when compatible whole-home humidity-control equipment is connected to your HVAC system.
Humidity settings can help improve comfort during both heating and cooling seasons.
